We can't judge people that they ask useless questions, because maybe they think it is a good question. What is good for us is not good for others, your fingers in your hands are not the same so you can't judge people.
Here we are all from different countries and different cultures, also different backgrounds, so we all think differently.
Also some people need money and try to find a gate online and they are trying their best to ask questions but they lack experience.
Also we can skip the useless questions if we don't like it , no one force us to answer it.
